Constraint Based Geometry
Geometry Expressions is a constraint based geometry system. The benefits of this type of system are:
- Many geometric configurations are much more easily specified using constraints than constructions
- It is a much more convenient style for expressing real world problems
- This is the approach used in modern Computer Aided Design (CAD) systems
Symbolic Geometry
In Geometry Expressions if you put symbols in as the values of constraints, you get symbolic expressions out for measurements (see above figure). This means:
- Reinforcing multiple representations (geometric and algebraic) of the same problem
- Symbiosis with CAS (like Maple, Mathematica, Nspire, ClassPad Manager)
- Makes the geometry software extremely relevant in algebra, precalculus and calculus courses, as well as in university and professional engineering contexts.
“The best thing about Geometry Expressions is the ease of use. GE has very convenient menus and one can do nice things like specify lengths of segments and have them appear as desired.
